Au delà de la syllabe : le rôle des informations articulatoires stockées dans le lexique pour l'analyse de la chute de schwa
Résumé
This study presents data showing articulatory differences between a sequence of consonants resulting from the loss of schwa and underlying consonant sequences. For example "d'rôle" 'some role', with the apostrophe indicating schwa loss, remains articulatorily distinct from "drôle" 'funny'. These differences involve non contrastive phonetic details such as amount of linguopalatal contact and aspects of inter-gestural coordination. Whereas distinctions such as "d'rôle" vs. "drôle" have been interpreted in the past as stemming from different syllabic structures, we propose an alternative. The comparison between the schwa-elided form ("d'rôle") with the lexical form containing schwa ("de role") demonstrates that the properties which set apart forms like "d'role" from underlying clusters ("drôle") represent in fact fine articulatory characteristics of the lexical form, which are maintained in the surface variant without schwa. These results provide evidence for including certain non-contrastive phonetic properties in the inventory of invariant characteristics of lexical entries.
